Part Number: PCM4202 Other Parts Discussed in Thread: PCM4204 Hi Sirs,
My customer ask there have the curve of THD+N vs signal level? They only found the curve of THD+N vs amplitude on the PCM4202 datasheet.
example: PCM1804 datasheet
Hello,
Can I ask two additional questions about the PCM4202 and PCM1804 I asked earlier?
(4) Change digital filter settings
Looking at the filter characteristics, it seems that the PCM4202 and PCM1804 both have a digital filter setting that limits the…
Part Number: PCM4202 Hello,
Our customer plans to increase bypass cap value from 0.1uF on application circuit to optimize sound character.
What is internal Vcom buffer output node stability or start up timing issue? Can we increase it to like 470uF?

Part Number: PCM4202 Other Parts Discussed in Thread: OPA1632 Hi,
in the PCM4202 data sheet, there's a recommended Input buffer schematic based around a OPA1632. (see attached screen capture)
The input impedance seems pretty low for professional line…
Part Number: PCM4202 Other Parts Discussed in Thread: PCM4204 Hi,
In order to input a single-ended signal to PCM4204 with minimum space/component requirements, despite high performance, is it possible to use a single OpAmp as specified in this design…
Thanks Colin, I was off looking at other things, but this is useful,
Yes, I have decided you cannot just float the Vocm on the FDA due to low frequency noise (here,I am aiming at a 2Hz to 50kHz span for a measurement mic). I could drive the Vocm directly…
Part Number: PCM4202 Other Parts Discussed in Thread: PCM1861 Hello,
Regarding to PCM4202, my customer is asking a question.
They will replace to PCM4202 from AK5359.
AK5359 is single end input but PCM4202 is deferential input.
(Question)
Can PCM4202…
Part Number: PCM4202 The PCM4202 can be operated in 3 sampling modes: single rate, dual rate, and quad rate.
Single rate --- upto 54KHz
Dual rate --- 54Khz-108KHz
Quad rate --- 108KHz-216KHz
There are 3 pins FS0,1,and 2 which determine the sampling…
Part Number: PCM4202 Hello sir,
We need to implement VU meter Indication for incoming audio signal. Because We have plan to control VU meter LED's through Processor GPIO's
Any possibility of measuring Decibel level of Audio signal in PCM4202…
Part Number: PCM4202 Other Parts Discussed in Thread: OPA1632 Hi Team,
Would you advise about below two questions?
1. There is a description of "Each analog input pair accepts a full-scale input voltage of
approximately 6.0VPP differential on page…
